Convert module over to ruby-pwsh

[nmaludy]

ruby-pwsh has proved to be a huge time saver in some of our other modules, we should convert this one over to use that library and take advantage of cached powershell runtimes!

The performance is horrible in its current state. Seeing 15-20s in convert catalog, I think because of non optimized ps runtimes. Makes this unusable.
